Supersnow's assumption is correct. Remember that I called it a "Warrior-style", so it doesn't need to have the same combo restrictions. Making the combo unbreakable by healing and assigning it to a single button, similar to PCT, would eliminate most justification for greed.
Another adjustment that would prevent issues is extending the duration of the spells relative to Inner Release and Primal Rend.
I'll put the rest of my armchair job design idea in a dropdown, so I don't make this reply too long.
I believe the best healer to fit the Warrior playstyle would be the Sage. If Phlegma were changed to cost 50% of a new gauge meter, many skills could be easily adapted to the job:
- 1-2-3 single-target combo = Dosis combo
- 1-2 AoE combo = Dyskrasia combo
- Storm's Eye = Eukrasian Dosis
- Fell Cleave/Decimate = Phlegma
- Upheaval/Orogeny = Psyche
- Onslaught = Icarus
- Infuriate = New button
- Inner Release = New button
In my mind, these changes alone would make Sage significantly more engaging to play, requiring only two new buttons and an extra gauge.
